Our work focuses on understanding the effects of climate change on livelihood realities and development perspectives of especially vulnerable population groups. Impact and vulnerability assessments provide an important basis for the identification of adaptation requirements as well as analyses of loss and damage. Through assessing the implications of impacts at different levels of warming, we gain a better understanding of the implications of different emission pathways. SIDS and LDCs face particularly great challenges. Their physical exposure and the limited number of available adaptation options as well as adaptive capacity are key determinants of their vulnerability.


This article contains the review of scientific evidence of regional differences in climate hazards at 1.5°C and 2°C and provides an assessment of selected hotspots of climate change, including small islands as well as rural, urban, and coastal areas in sub-Saharan Africa and South Asia, that are particularly affected by the additional 0.5°C global mean temperature increase.  
To support implementation of the Paris Agreement, the new HAPPI ensemble of 20 bias-corrected simulations of four climate models was used to drive two global hydrological models in worlds approximately 1.5 °C and 2 °C warmer than pre-industrial. Seven hydrological hazard indicators were analysed characterizing freshwater-related hazards for humans, freshwater biota and vegetation. The findings show that areas with either significantly wetter or drier conditions are smaller in the 1.5 °C world for all but one indicator. The incremental impact between 1.5 °C and 2 °C on high flows would be felt most by low income and lower middle income countries, the effect on soil moisture and low flows most by high income countries.  
Climate Analytics’ submission to the Talanoa Dialogue summarises the latest scientific findings relating to the 1.5°C limit. It outlines what climate impacts are being experienced around the globe at the current level of warming of around 1°C, such as extreme weather events, more intense tropical cyclones, impacts on oceans systems and health. It also discusses the benefits of the 1.5°C limit in terms of avoided impacts, especially on the most vulnerable communities, and what is needed to limit warming to 1.5°C.  
This article investigates projected changes in temperature and water cycle extremes at 1.5°C of global warming, and highlights the role of land processes and land-use changes (LUCs) for these projections. It is is part of the theme issue ‘The Paris Agreement: understanding the physical and social challenges for a warming world of 1.5°C above pre-industrial levels'.  


IMPACT is a cross-cutting, multi-faceted project that aims to strengthen the connections between the scientific assessments of climate impacts, vulnerability and adaptation to help enable access to finance and help Small Island Developing States (SIDS) and Least Developed Countries (LDCs) implement concrete projects.  
This project provides francophone Least Developed Countries in Sub-Saharan Africa with science-based support when formulating their National Adaptation Plans (NAPs). In addition, it will give these countries access to international climate finance and establish national, international and regional platforms to share knowledge and experiences.    
The EmBARK-project will investigate time scales and possible trajectories of socio-economic transformation processes and analyse their relevance as potential barriers to adaptation to climate change. An improved understanding of the temporal dynamics of such barriers is key in developing a more realistic understanding of future climate impacts and for scientifically robust assessment of future climate related loss and damage.  
The "Climate Action Tracker" is an independent science-based assessment, which tracks the emission commitments and actions of countries.  
The Caribbean region is highly exposed to tropical storms, hurricanes, flooding, and naturally induced disasters. These hazards represent a significant risk to the inhabitants and economies of the Caribbean countries. The Climate Risk Adaptation and Insurance in the Caribbean (CRAIC) project assists Caribbean countries in their efforts to increase social resilience and adapt to climate change by incorporating climate risk insurance within a broader framework of disaster risk reduction strategies.  
SLICE is investigating Short- and Long-Term Impacts of Climate Extremes and aims to develop a systematic understanding of the channels through which climate extremes impact socio-economic development all the way from the household to the macroeconomic level. This will help developing effective strategies for long-term economic development under climate change.
